oliverschmidt 5f3296e943 Changed packet drivers from services to plain processes. 
Now tcpip_output() is a function pointer that is supposed to be set via the macro tcpip_set_outputfunc(). Packet drivers do so on process startup.

Thus if there are several packet drivers in a Contiki system the one started last is the one actually used. This behaviour is especially useful for the 'IP forwarding' "meta" packet driver.

oliverschmidt 9f97290665 Changed Contiki File System (cfs) from a service to a plain library. 
This change means that one needs to select _ONE_ cfs implementation at Contiki library link time. But this doesn't appear to be an issue as all platforms have their "favorite" implementation anyway.

bg- 5fb8871fb6 * NULL pointer spotted by Vlasios. 2007-05-13 15:14:48 +00:00
oliverschmidt 4832e803e8 Made use of signed 32 bit data type. 2007-05-12 21:04:05 +00:00
bg- 813b27d234 * Add last two relocs. 2007-05-11 15:40:16 +00:00
bg- 82aa4b4926 * When looking up potentially bad routes use uaodv_rt_lookup_any 
rather than uaodv_rt_lookup.
 2007-05-09 16:45:03 +00:00
bg- faf94db265 * Respect "destination only" flag in RREQs. 
* If our routes seqno is <= requester last known seqno our route must
  be bad (in his eyes). Previos comparison was < which must be wrong.
 2007-05-09 14:53:54 +00:00
bg- 34490eeecb * Make it explicit that some seqno:s are in host byte order by naming 
them hseqno.

* Change uaodv_rt_add to take argument in (standard) network byte
  order (and change it to be a pointer).

bg- 9cde72c806 * Make filtering criterion on rssi more liberal and don't use the 
correlation value at all.

bg- c23e583129 * Added flag UAODV_RERR_UNKNOWN to deal with unknown errors that are 
often the result of rebooting nodes.

bg- a207770a1e * Add attribute to track bad routes and necessary support for this. 
* Revamp forwarding to deal with bad routes or request new routes as
  appropriate.

* Mark bad routes (rather than tossing them) as we are informed by
  other hosts.

* No longer wait two ticks before making route request.
